BATH CABENET.

Application tied July 1,

Be it known that we, Feen-n Haino and JoHN Sci-Imaz, citizens of theUnited States, residing at Cicero and Chicago, respectively, in thecounty oit Cook and State oit illinois, have invented new and usefulimprovements in Bath Cabinets, ot' which the following is aspeciiication.

This invention relates to apparatus for applying' hot air or vapor tothe body ot persons as a treatment for the reliei' or cure of certainbodily ailments', and more particularly to apparatus oi' this kindcharacterized by an enclosure for the body and a means for heating theair within the enclo sure.

The invention has for its object to pro-vide a very simple and highlyeiiicient apparatus of the kind stated, and to this end it consists ina. novel combination and arrangement of parts to be hereinafterdescribed and claimed.

In order that the invention may be better understood, reference is hadto the accompanying drawings forming a part of this speciication, and insaid drawings,

Figure 1 is a perspective view of the apparatus;

Fig. 2 is a central longitudinal section thereof;

Fig. 3 is a cross-section;

Fig. 4 is a horizontal section on the line 4-4 of Fig. 2, and

Fig. 5 is an enlarged cross-section on the line 5 5 of Fig. 4.

Referring specically to the drawings, the enclosure for the body issubstantially semicircular or arched in cross-section, and it iscomposed of a skeleton frame work and a covering 10 of suitable materialwhich is air-tight or substantially so. The traine supporting thismaterial is composed of transversely arched end bars 11 and longitudinalbars 12 connecting the same. One end of the enclosure is closed by anend flap 13, and the other end is closed by an end flap 14 formed withan opening or gap 14'm for the atients neck. The patient lies on asuitale support on which the device is placed to completely enclose thepatient with the exception of the head, the neck passing through the gap14a.

The means for heating the interior of the enclosure consists of twoheating chambers, one of such being positioned on one side of 192i.serial ne. 451,854.

the enclosure', and the other on the opposite side, and both beinginside the enclosure.

Each heating' chamber consists oi a sheet metal casing 15 which seatsagainst the side ot the enclosure and is secured thereto in any approvedmanner, it being curved to conform to the curvature thereof. The casingextends in the direction oi' the length o1 the enclosure and it isnositioned midway between its ends and has a sufficient length to supplythe requisite volume of hot air. rlhe casing also has an upward taper,as clearly shown in F 3, and it is closed at its ends and at the top.

ln the side wall of the casing 15 which faces the interior ot theenclosure are air inlet apertures 16, and air outlet apertures 17, the'former being near the bottom and the latter near the top of the casing.

ln the casing 15 is mounted an electric heating element consisting of ahelical resistance element or coil 18 seating on a hori zontal baseplate or partition 19 over a slot 2O in the latter. The plate 2O is, oicourse, composed of a suitable non-conducting material, and it issecured in the casing near the bottom thereot1 by brackets 21. The plate19 extends throughout the entire length and width of the casing, andhence the latter is here closed except at the slot 20. The plate 19 islocated above the air inlets 16, and the air outlets 17 are above theplate.

Suitable circuit connections for the resistance coils 18 will beprovided, together with a switch, and as these torni no part oi thepresent invention they need not be described. lt may be stated however,that a switch should be provided to make it possible to cut in eitherone or both resistance coils according to the degree of heat desired, orwhichever side of the patient is to be eX- posed to the heat.

The casing 15 has an inner lining 22 of asbestos paper.

When the apparatus is in operation, the heated air escapes from thecasings 15 through the top outlets 17 and cool air is drawn into thecasings through the bottom inlets 16. rllhe air rises through the slots2O and it is heated as it comes in conta-ct with the hot resistancecoilsI 18. rlhere is thus maintained a constant circulation of air inthe enclosure and the heated air is distributed to all parts or" theinterior thereof. The enclosure becomes heated very rapidly f outletsthereof.

'with the expenditure of but a small amount heating chambers in theenclosure along opposite sides thereof, said chambers having bottom airinlets from the interior of the enclosure, and top lair outlets into theinterior of the enclosure, and heating elements in the chambers betweenthe air inlets and 2. A bath cabinet comprising an enclosure, heatingchambers in the enclosure on opposite sides thereof, said chambershaving bottom air inlets from the interior of the enclosure,and top airoutlets into the interior of theenclosure, a partitiony in each chamberbetween the air inlets and outlets thereof, said partition having alongitudinal slot, and a heating element seating over the slot.

3. A bath cabinet comprising an enclosure, heating chambers in theenclosure along opposite sides thereof, said chambers having bottom airinletsfrom the interior of the enclosure, and top air outlets into theinterior of the enclosure, a partition in each chamber between the'airinlets andoutlets thereof, said partition having a longitudinal slot,-and an electric resistance coil seating over the slot. p

4f. A bathcabinet comprising an enclosure, heating chambers in theenclosure along opposite sides thereof, and supported by -said sides,said chambers having bottom `air inlets from the interior of theenclosure, and top air outlets into the interior of the enclosure,

`and heating'elements in the chambers between the air inlets andoutletsthercof.

5. A bath cabinet comprising an enclosure which is open at the bottom,heating chambers in the enclosure on opposite sides there of, saidchambers having bottom 'air inlets from the interior of the enclosure,and'top airoutlets into the vinterior of the enclosure, and heatingelements in the chambers be'- tween the air inlets. and outletsthereof.-

In testimony whereof we al'lix our signav tures. v FRANK HNILO. JOHNSCHULTZ.
